I need some information about the timing triggers on the 20vt engines.

Hi,

A guy asked me some things about what needs to be done with the triggers
when installing a S4 engine in an urq, I found that I had misunderstood a
few things about the triggers on the 20vt engines. Motronic for me is the
same as a 60-2 trigger wheel but the way he described it it looked just like
on the 10vt engine, one crank sync pulse and one pulse per tooth on the
flywheel. Is this correct?

What kind of trigger is on the cam? Is it a single sync pulse for
compression TDC or is a standard 60-2 trigger wheel installed there?
